INSTALLATION INSTRUCTIONS Pressure and flow controllers DPT-Ctrl-MOD Series INTRODUCTION WARNING Thank you for choosing an HK Instruments DPT-Ctrl-MOD series air handling controller with differential pressure or airflow transmitter. The DPTCtrl-MOD series PID controllers are engineered for building automation in the HVAC/R industry. With the built-in controller of the DPT-Ctrl-MOD it is possible to control the constant pressure or flow of fans, VAV systems or dampers.

SCHEMATICS STEP 3: CONFIGURATION 1) Press the select button for two seconds to open the device menu. 2) Zero point adjustment. For more information, see Step 4. Input terminal conﬁguration jumpers SELECT SELECT ZERO SENSORS LEDs UP DOWN Joystick 1 Select Pressure sensor Display connection Joystick 2 Up Joystick 3 Down Menu buttons A Control out B GND 24 V Input GND GND 3) Select the functioning mode of the controller: PRESSURE or FLOW.

CONFIGURATION CONTINUED STEP 4: ZERO POINT ADJUSTMENT 5) Select the baud rate: 9600/19200/38400. NOTE! Always zero the device before use. Supply voltage must be connected one hour before the zero point adjustment is carried out. Access via Modbus or by push button. 1) Loose both tubes from the pressure inlets + and -. 2) Activate the device menu by pushing the the select button for 2 seconds. SELECT 3) Select Zero sensor by pressing the select button.

STEP 7: Fixed output MODBUS REGISTERS CONTINUED Fixed output settings can be enabled to set the control output to a preset value. Primary purpose of this functionality is to enable the adjustment of air valves and terminals without the DPT-Ctrl affecting the duct pressure or air flow. It can also aid in troubleshooting the installation. Function code 04 - Read input register Register Parameter description Data Type Value Range 3x0001 Program version 16 bit 0...1000 100...
